Listening to Karasawa's preaching, Koshimi Nanatsuki didn't feel unconvinced at all, but instead humbly admitted his own shortcomings.
She agreed to come to be Tang Ze's assistant in order to learn better from Tang Ze's side, and she also hoped to have someone with a higher level to guide her.
Although Tangze usually treats her as a tool to handle administrative work and fish for himself, when he encounters a case, he can reveal the other party's true strength.
You must know that the two of them were investigating the case together, and except for the scene where the body was dumped, they acted together throughout the whole process.
But he didn't find any clues, but Tangze caught some inconspicuous clues in the conversation, and directly found the cause of the food poisoning from the small detail of "the taste was wrong."
This also allowed her to discover where she was lacking and learned a lot from it.
"Okay, just go back and read more if you have nothing to do." Tang Ze saw that Yueshui had listened to what he said, so he didn't say much. Instead, he smiled and said: "You can read any book if you are interested. Maybe
It will come in handy someday."
"Understood." Koshimizu Nanatsuki nodded and then asked: "Senior, are we going to the murderer now?"
"It seems you also know who the prisoner is?" Tang Ze said with a slight smile.
"I can't tell the food poisoning aspect, but that doesn't mean I don't know who the murderer is."
Koshizui Nanatsuki rolled his eyes: "There are so many clues. If I don't know anymore, then my job as a detective will be in vain."
"Then let's go directly." Tang Ze threw the car keys to the other party casually: "Let's visit this murderer, who is also the other culprit of food poisoning."
"I'm becoming more and more a coolie."
Taking the car key, Koshimizu Nanatsuki couldn't help but muttered.
Opening the passenger door, Karasawa glanced at Nanatsuki Koshimizu and said, "Do you think it's appropriate for the leader to drive and the secretary to sit in the passenger seat?"
"Hey, that's not to say that our relationship is unusual." Koshizui Nanatsuki heard this and chuckled, "The normal workplace relationship doesn't apply to us~"
"Don't be poor and watch the road carefully." Tang Ze saw the car start slowly and immediately reminded him: "I remember you have driven a few times after you got your driver's license, right?"
"Yes, after all, I don't have money to buy a car." Koshimizu Nanatsuki showed a narrow smile: "What's wrong, do you regret letting me drive?"
"It's because I know that I let you drive. Didn't I say that you still have a lot to learn? Naturally, driving is also part of it." Tang Ze said calmly: "As long as I'm here, nothing will happen."
After all, it is S-class driving skills, and the factory is not full of people in the city. As long as the speed is not particularly fast, Tang Ze is still confident to guide a newbie on the road.
Even if Koshimi Nanatsuki suddenly panicked and stepped on the accelerator instead of the brake, and he turned the steering wheel with one hand on the co-pilot's non-dominant hand, his neurological reaction would be enough to make the most appropriate judgment.
By this time, Koshimizu Nanatsuki also knew that Karasawa wanted her to practice driving, so he started driving seriously.
Although he was a novice on the road, he still had a driver's license after all. Koshimizu Nanatsuki had a smooth journey to the Ikedo Food Processing Factory.
After meeting Iketo Makoto, the two placed the photo of the seized soup processing machine on each other's desk.
"We identified areas of the sauce machine that had to be dismantled before they could be sanitized and discovered the ingredients of the special sauce you provided to the happy hour restaurant."
Koshizui Nanatsuki looked at the shocked Iketo Makoto coldly and said: "At the same time, we also checked for food poisoning bacteria.
In other words, this processing machine is the source of pollution that caused hundreds of people to be poisoned."
"How could this happen?" Ikego Cheng picked up the machine identification certificate in disbelief: "Could it be said that it is time for regular inspection..."
"That's right." Karasawa nodded and said, "Their president, Miura Tatsutatsu, lacked the necessary technical personnel due to the expansion of the factory, so he did not inspect this machine."
"So that's it. No wonder the soup tastes wrong."
Ikego Makoto shook his head repeatedly when he said this, and then looked at the two of them expectantly: "Then if that's the case, then it's not our company's fault, right?"
Speaking of this, Ikego Makoto also pointed his fingers excitedly: "I'm here with Lichen Machinery who is inspecting this machine!"
"You think you are not at fault, right?"
Karasawa's tone became colder: "I asked the happy hour restaurant, and they said that the scallops used in the sauce are high-end ingredients that can be eaten raw.
And they also showed us the type of scallops specified by their boss at Maruyama Food Company.”
"It also clearly says "Eat raw" on it." Koshimi Nanatsuki took out a blue sealed bag and placed it on the table.
After that, without waiting for Ikego Makoto's reaction, he took out another sealed bag with red packaging: "And this red one, it clearly says "Heat and eat". This kind of shellfish must be heated because there are too many bacteria attached to it."
Eat it when it's cooked.
The kind designated by Happy Restaurant will not contain Vibrio parahaemolyticus even if it is eaten raw.
Our colleagues in the Living Environment Section have inspected Maruyama Foods, and their blue bag "raw" scallops are fully qualified."
"In other words, the problem not only occurs on the machine, but also on you!
In your greed for profit, you used the cheap "heated and eaten" scallops in the red bag as ingredients for making the sauce and added them to it, right?"
Karasawa looked at Ikedo Makoto, whose lips were trembling, and his tone became colder: "You should have discovered something was wrong with the machine the night before the mass poisoning incident, right?
But you couldn't contact the Time Restaurant to get the things back, because you killed Akiko Hinomori here that night.
On the neck of Ms. Johnson Akiko's corpse, there were unique scars from the heating rod of the soup processor.
And only you were most likely to check the machine yesterday, thus pushing it over and hitting the heating column after the conflict between the two of you."
"Don't talk nonsense!"
When Ikedo Cheng heard Karasawa's words, he slammed the table and jumped up: "Don't slander people!! You don't have any evidence that she was killed here!
And I’m not the only one with this machine!”
"This is because you cleaned and sterilized the heating column, and then made a pot of soup to clean up the blood stains because you were worried, but we have other evidence."
Karasawa took out a photo of the salad oil specially provided during happy hour: "We have compared this salad oil with the oil on the soles of the deceased's shoes. They are exactly the same. Is this also produced at your place?"
"In addition, there are boxes that can be seen everywhere in your factory."
Koshimizu Nanatsuki opened a cardboard box: "The same resin as this was found on the inside of the victim's shoe sole.
I guess after you killed the person, you put the body of Miss Hideo Senakiko in this big cardboard box, took it away and dumped it on the forest road, right?"
"Salad oil and boxes are two things, and happy hours are also available!"
Ikego Cheng panicked when he heard the female criminal in front of him accurately reconstructing the matter. He looked at the two of them and roared: "Evidence, show me the evidence. What you said is just speculation and slander!"
"What are you arguing about? Whoever has the loudest voice is not justified." Koshizui Nanatsuki looked at Iketo Makoto and snorted coldly: "Do you think our criminal cases are all based on conjecture!"
"Compared to the fact that before Akiko Jiangmori died, the soles of her feet were stained with salad oil."
Tang Ze said calmly: "I guess I accidentally bumped into the pile of salad oil piled in the corner of the factory while pushing you, right?
And this also provides us with decisive evidence. If we can detect the footprints of Ms. Akiko Bijimori that were stained with salad oil before she died, we can be sure that this is the scene of the crime.
If your footprints were stained with salad oil at the scene, I think that would be enough to convict you.
Moreover, the car you drove to dump the body was also found by my colleagues relying on surveillance along the way. This evidence is enough to confirm that you are the murderer!"
There is no lie in what Tang Ze said. Even if these proofs are cleaned up by the other party, as long as they are not cleaned up in a particularly professional way, the Science Search and Research Institute will find a way to reveal them.
And knowing that the target is different from finding a needle in a haystack, even if the evidence is insufficient, it is not difficult to find evidence as long as you focus on the other party.
Tangze and others had not found any obvious footprints before, but those were no specific clues.
What the police are most afraid of when appraising evidence is "checking to see if there are any problems." In this way, all blood stains, chemicals, virus tests, etc. will have to be tested.
But if you have a specific direction, such as checking for blood stains, then the corresponding luminol can be found. The same is true for other tests, and there are reagents or machines for corresponding tests.
So even if the lush grass covers the obvious footprints, the grease may be directly contaminated on the grass.
If you send people to investigate, you will naturally gain something.
After hearing Karasawa's words, Ikego Makoto could no longer stand still. He stumbled and sat directly on the seat, feeling fearful and painful.
But looking at the remorseful Iketo Makoto, Karasawa and Koshimi Nanatsuki had no sympathy for him.
His crying and regret were a vent for everything in his future and regret for killing someone, but they were not guilt and repentance for killing Miss Johnson.
Tang Ze had seen a lot of people like this who didn't show any remorse to the deceased after killing someone, and he had no sympathy for him at all.
After taking Ikedo Makoto back to the Metropolitan Police Department for interrogation, the other party honestly told everything that happened that night.
That day, there was something wrong with the sauce produced by the soup processing machine, which caught his attention.
After all, they are all the same raw materials and ingredients, and they are all made by the same machine, so how can there be any change in taste?
So Ikego Makoto thought there was something wrong with the machine, so after the soup was finished and cleaned up, he waited until everyone left and pulled out the heating rod to check the situation.
But before he could take the next step, Miss Bee Johnson came to visit.
She noticed that the quantity of two types of scallops purchased by Ikedo Makoto had increased and decreased significantly recently.
Naturally, the purchase volume has declined for the expensive blue-bag scallops that can be eaten raw, while the purchase volume has increased naturally for the "heated and edible" red-bag scallops.
Because she was the one who introduced the cooperation between Happy Hour Restaurant and Ikedo Processing, she felt something was wrong and came over to visit.
Ikedo Makoto originally planned to prevaricate, but he never expected that Miss Hideo Johnson would come today.
And the red scallop bags they used to make the sauce were piled in the corner without a chance to be disposed of.
Then Ms. Hijimori discovered the secret of Ikedo Makoto secretly substituting scallops to make sauce. Ikedo Makoto said that there was no profit in using blue bag scallops and he couldn't make much money at all.
But from the perspective of Hiko Mori Akiko, Ikego Makoto is undoubtedly a betrayal of her.
She kindly introduced her factory to establish a cooperation with Happy Hour Restaurant, but the other party did not abide by the contract and purchased low-quality scallops, causing the sauce to taste bad.
So Akiko Hinomori planned to inform the owner of Happy Hour Restaurant about this matter and end the relationship between the two parties.
Akiko Biemori is a serious girl. She felt that what caused this was that she introduced an untrustworthy company, so she planned to apologize and resolve the matter.
But she still underestimated human nature.
When she took out her mobile phone, Ikego Makoto reached out directly to grab her mobile phone. After all, the two parties signed a contract, and if they breached the contract, they would have to pay a large amount of compensation.
During the scuffle, the two hit the salad oil next to them, which is why there is salad oil on the soles of Johnson Akiko's shoes.
During the scuffle, Ikego Makoto, who was benefiting greatly, became anxious and pushed Akiko Hinomori down in an attempt to take the opportunity to seize the phone.
But what he didn't expect was that unlike the previous factory environment, he had pulled out the heating column of the soup processing machine today.
Then because of this push, Akiko Hideo directly hit the heating column next to it.
Due to the violent impact on her neck, Akiko Hideo was unable to react for a while, and her head hit the sharp corner of the machine.
The human body is sometimes very strong, but sometimes it is so fragile, especially if you fall flat on the ground or your whole body is bruised, but if your head hits a sharp corner, you may just send it away.
However, after Akiko Biemori hit her neck and was hit by the impact, her body was unable to make subconscious protective actions such as supporting her arms, and she fell directly to her death.
It was only at this time that Ikego Makoto realized what he had done.
But fortunately it was already after get off work and no one else was in the factory. After he calmed down, he dealt with the crime scene.
Then he put the body of Akiko Hinomori into a box and drove the body to a remote forest road.
After killing people, he naturally had no energy to pay attention to the processing machines. He was probably in a state of panic all night.
But what he didn't expect was that a big problem would arise after he ignored the malfunctioning soup processing machine.
As many as hundreds of people were suffering from food poisoning, and he was immediately swept away.
If it was just a simple murder case, even Tang Ze would probably have to investigate for several days to find the culprit. After all, the two of them had no conflicts before, and his murder was an accident.
But it is precisely because of this food poisoning that everything is connected.
